2. Description of the Prior Art

Dating back to ancient time, people start delivering information byrecording information on surfaces of various objects. For example, sincethe birth of paper, people acquire the information through charactersand drawings affixed on papers. Furthermore, in recent years, withdistinctive colors, characters, or pictures attached to differentlocations on surface of an object, people try to disclose theinformation with regard to each different position of the object.

When people observe the surface of object, they generally capture theinformation visually. However, the amount or types of the informationcarried by the surface of object are generally limited under therestrictions of the area size, beautification of the surface.

Nowadays, due to the advance of electronic technology, the visualinformation has been retrieved from its original carrier and stored asthe digital information in an electronic apparatus. And people read themdirectly from the electronic apparatus. However, it is difficult for thedigital information to totally replace the information printed in booksor information attached to the surface of object.

On the other hand, through hyper link approach of computer technology,the digital information can be displayed in multiple dimensions, whilethe information printed in book or attached to the object still aredisplayed in two dimensions. Thus, if multiple dimensions informationcan be recorded on the book or the object, people can acquire additionalinformation through the electronic apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention provides a method for producing graphicalindicators and interactive systems for utilizing the graphicalindicators. Some visually negligible graphical indicators are affixed onthe surface of an object. The graphical indicators co-exist with a maininformation, such as a text or picture, on the surface of object, and donot interfere with the perception of human eyes to the main information.A user retrieves the graphical indicators through an electronic systemand acquires additional information from the graphical indicators. Theuser can utilize the graphical indicators without a complicated platformproviding coordinate system. Furthermore, the typical book or thesurface of object can carry more information through the graphicalindicators.

(A) Exemplary Design for the Graphical Indicators

In the present invention, one aspect of the graphical indicators is thatthe graphical indicators are so visually negligible that do notinterfere with the main information on the surface of object. Anotheraspect of the graphical indicators is that the graphical indicators arenot interfered by the other information on the surface when theelectronic system reads the graphical indicators.

For the visually negligible feature of graphical indicator, eachgraphical indicator includes multiple graphical micro-units arranged ina layout. Shown in FIG. 1(A), which has scale of 2.5:1, the combination100 of the graphical micro-units in a background to “APPLE” is thematrix consisting of graphical micro-units. The micro-units can bereduced further such that the combination 100 of the graphicalmicro-units is visually negligible or is viewed as a background materialby human eyes.

In practical application, the shape of the graphical micro-units may beregular or irregular shape, such as a round spot. For best result, thegraphical micro-unit must be so tiny that only a microscope apparatuscan detect it.

When the graphical micro-units are tiny and arranged loosely in thelayout, the user easily neglects the combination 100 of graphicalmicro-units and pays attention to main information, like the word“APPLE” depicted in FIG. 1(A). Next, we explain how to use the graphicalindicator to carry information.

The combination 100 of the graphical micro-units consists of multiplegraphical indicators arranged in sequence. Each graphical indicatorincludes multiple state zones for selectively respectively storing thegraphical micro-units, wherein each of the state zones displays a statefrom at least two candidate states.

For example, shown in FIG. 1(B) is an enlarged diagram illustrating oneof the graphical indicators in FIG. 1(A). The graphical indicator 11includes 36 units of state zones 113 in the form of 6 by 6 matrix. Eachstate zone 113 selectively includes one graphical micro-unit or does notinclude the graphical micro-unit to represent the first or second state.

When the micro-units in state zone 113 of the first state are assignedvalue of one and those of the second state are assigned value of zero, abit matrix form 114 shown in FIG. 1(C) is resulted. Thus, the bit matrixform 114 stores a variety of information as expected or desired. Inother word, the user can store desired information based on thecombination of different values of the state zones.

Furthermore, the multiple graphical indicators, as well as the graphicalmicro-units, are arranged in two-dimension matrix forms. Sucharrangements of the graphical indicators and the graphical micro-unitslook homogenous to human eyes. Next, the present invention provides amethod for retrieving the individual graphical indicator from the matrixform of the graphical indicators.

Shown in FIG. 1(B), which has scale of 100:1, the graphical indicator 11includes a header information 111 and a content information 112 arrangedin a layout that corresponds to different indicator information. In oneembodiment, all header information 111 are identical among differentgraphical indicators 11. However, for a more comprehensive design, morethan one set of header information may be employed as long as eachheader information within each graphical indicator is capable ofdistinguishing the corresponding graphical indicator from adjacentgraphical indicators and indicating the orientation of the correspondinggraphical indicator to the optical device. On the other hand, differentvalue of content information 112 represents different indicatorinformation. Thus, one graphical indicator 11 is read through capturingone header information 111, and the graphical indicator 11 does notinterfere with each adjacent graphical indicator 11. However, in anotherembodiment, the header information 111 in one graphical indicator 11 maybe different from that of other graphical indicator 11 as long as thesystem can use the header information to retrieve the correspondingcontent information.

FIG. 1(D), which has scale of 120:1, is a schematic diagram illustratingthe two-dimensional matrix form in accordance with the presentinvention. The user first searches the header information 111 andfurther retrieves the graphical indicator 11 and the correspondingcontent information 112.

Furthermore, in order to rapidly retrieve the indicator information, theimage corresponding to the matrix form of the graphical indicators isrotated and converted into bit matrix form, shown in FIG. 1(F) duringthe process.

Furthermore, we divide the surface of object into multiple index zones.Each zone corresponds to an index value. The graphical indicatorcorresponding to identical indicator information is repeatedly arrangedin each index zone. The graphical indicator corresponding to differentindicator information is repeatedly arranged in different index zones.The system maker of the invention records the corresponding relationshipof the indicator information to the index zone in an electronicapparatus. When the electronic apparatus captures an image from a indexzone, it can acquire the index value of the zone using the correspondingrelationship.

For example, FIG. 1(E), which has scale of 20:1, is an enlarged diagramillustrating the index zones and the graphical indicators in accordancewith the present invention. The graphical indicators 11 corresponding tosame indicator information are arranged in the index zone 12. Thegraphical indicators corresponding to different indicator informationare respectively arranged in the other index zones.

Other embodiment for the graphical indicators is possible. For example,FIGS. 2(A)-2(C) are the diagrams illustrating other embodiments for thegraphical indicators in accordance with the present invention. Shown inFIGS. 2(A)-2(C), a vertical segment represents the first state, and ahorizontal segment represents the second state.

Furthermore, FIG. 2(D) is the diagram illustrating other embodiment forthe arrangement of the graphical indicators in accordance with thepresent invention. Different from the matrix arrangement in FIGS.1(A)-1(F), a cellular arrangement is set forth in FIG. 2(D).

Alternately, different graphical indicators may also be arranged in oneindex zone as shown in FIG. 2(E). The letters “A”, “B”, “C”, and “D”respectively represent four different graphical indicators correspondingto four different indicator information. These four different graphicalindicators are repeatedly arranged in sequence within one index zone,shown in FIG. 2(E).

There are requirements for the graphical indicators being negligible tohuman eyes. First, each graphical indicator must be tiny and human eyescan not differentiate one graphical indicator from others. Second,according to the size of the graphical micro-unit, the pitch betweenmicro-unit, and the desired visual effect, one should reduce the numberof the graphical micro-units used. In this way, the graphical indicatorshave little influence on the brightness of the surface of object.Furthermore, number of graphical micro-units of each graphical indicatoris substantially equal to each other, and therefore the graphicalindicators look more homogenous to human eyes and become invisible tohuman eyes.

In a first embodiment, each square centimeter of the selected zoneincludes more than 3000 state zones of which less than seventy percentare in the first state, and percentage of area occupied by the graphicalmicro-unit in the state zone is less than 80.

In a second embodiment, each square centimeter of the selected zoneincludes more than 6000 state zones of which less than seventy percentare in the first state, and percentage of area occupied by the graphicalmicro-unit in the state zone is less than 80.

The following provides the methods for capturing the graphicalindicators by an electronic system without interference with maininformation on the surface of object.

First, a method utilizing infrared ray and oil ink is illustrated below.

While printing the information on conventional media, a desired color isobtained by combining primitive color inks: cyan (C), magenta (M),yellow (Y), and black (K). Generally, hue and saturation are obtained byadjusting combination of C, Y, and M, and brightness is obtained byadjusting K.

It is noted that infrared ray has high transmittance for most of C, M, Yprimitive color inks, but has low transmittance for most of K colorinks. In other words, C, M, Y color inks hardly absorb the infrared ray,but black color ink substantially absorbs the infrared ray. Therefore,infrared ray transmits through most of C, M, Y color inks and displayshigh brightness after reflecting from a light-coloured object surfaceunder C, M, Y color inks. On the contrary, the surface that is printedin black color ink displays low brightness because of the absorption ofthe infrared ray by most of black color ink. Thus, when a detectorreceives an image corresponding to graphical indicators printed in mostof black color ink, the image does not interfere with main informationprinted in most of C, M, Y color inks.

On the other hand, when the main information needs to be printed inblack, one type of black color, in the specification we called itNear_K, which hardly absorbs infrared ray, is used to print the maininformation. Mixing C, M, Y colors under predetermined ratio makesNear_K that displays visual black, such as dark indigo or dark brown.The ratio for mixing C, M, Y colors to obtain Near_K color is well knownto the people skilled in the art. Since Near_K is made by C, M, Y colorinks, Near_K is transmittable by infrared ray. And, to cooperate withthis arrangement, the graphical indicators are printed using K (black)color.

In the above description, the black color is used for an example and,however, it is not a limitation. Other inks that can substantiallyabsorb the infrared ray can be used to print graphical indicators. Thisapproach has advantage of low cost. It is to be noted that any type ofoil ink, no matter what color it shows, that could substantially absorbinfrared ray, are suitable for the print of graphical indicator and areintended scope of protection of present application. Any types of oilink, that are transmittable by infrared and are close to black visually,i.e. some oil ink of edibility-class without carbon element, can also beused as Near-K color. Near-K color may act as role of black color offour primitive colors (C,M,Y,K) while printing the main information overthe surface.

On the other end, it is known that most oil inks absorb ultra-violent orblue light. That is, they do not produce light in visible spectrum whenirradiated by ultra-violent or blue light. However, special type ink,such as fluorescent ink, produces visual image under the irradiation ofultra-violet or blue light. Thus, under this approach, the graphicalindicators are printed in fluorescent ink, and the main information isprinted in a typical oil ink. To cope with the arrangement,ultra-violent or blue light is used to irradiate the surface of objectwhile reading the image. Afterwards, the non-interference image can beobtained by implementing an optical filter for filtering out unwantedspectrum portion.

Another method is to directly use visual light. Since there are manygraphical indicators that are not overlapped with the main information,as long as the detector detects single graphical indicator, theindicator information can be obtained.

There are more than one approaches to generate (prepare) the indicatorinformation. For example, the additional information is encoded into theindicator information by method of compressed encoding. When theelectronic system retrieves the indicator information, it acquires theadditional information by decoding the indicator information. When thisapproach is adopted, the processing device of the invention, responsiveto the graphical indicators, acquires the corresponding additionalinformation by processing (decoding) the graphical indicators.

Another way to obtain the additional information from the indicatorinformation is using a mapping unit stored in the electronic system. Theembodiments of the mapping unit include a database or a lookup table,etc. Actual implementations for the mapping unit include a hard disk, afloppy disk, a compact disk, a read-only memory, or a memory card. Theelectronic system acquires the additional information corresponding tothe indicator information through the mapping unit. When this approachis adopted, the processing device, responsive to the graphicalindicators, acquires the corresponding additional information bytransforming the graphical indicators. Furthermore, for a morecomplicated design, the processing device, responsive to the graphicalindicators, acquires the corresponding additional information byprocessing and/or transforming the graphical indicators.

The active light source 612 of the optical-readingdevice 61 irradiates active light beam 613 onto the surface of object 64(step 71). The surface of object 64 absorbs the portion of the activelight beam 613 and reflects or scatters the light. The sensor unit 611captures the scattered light 614 through subsequent lens 615 and anoptic filter 616 to form an image (step 72) and converts the image intoelectronic information (step 73).

The sensor unit 611 transfers the electronic information to theimage-processing circuit 62 for image processing purpose. Theimage-processing circuit 62 extracts the combination of the graphicalmicro-units from the electronic information (step 74). The exemplarycombination of the graphical micro-units is denoted as 100 in FIGS. 1(A)to 1(E).
